class ComplexDataDefinitionNormalizer in Schemata 8

Normalizer for ComplexDataDefinitionInterface.

ComplexDataDefinitions represent objects - compound values whose objects have string keys. Almost all fields are complex in this way, with their key data stored in an object property of "value". In turn, these objects are wrapped in an array which is normalized by ListDataDefinitionNormalizer.
